Nanny for Google Chrome (TM)

Nanny for Google Chrome (previously Chrome Nanny) allows you to be more productive and less distracted by blocking sites.

First of all, Thanks for using Nanny for Google Chrome ! It was previously called Chrome Nanny.
Important : To use Chrome Nanny, right click on the Clock icon and select "Options" . If you cannot see it, then click on the wrench icon on the top right corner of Chrome and then go to Tools ->Extensions. Select the entry for Chrome Nanny and click on "Options" to go to page to configure Chrome Nanny. For detailed instructions on usage , see http://saravananthirumuruganathan.wordpress.com/2010/05/05/instructions-for-chrome-nanny-a-leech-block-like-extension-for-chrome/ .
Chrome Nanny is a Chrome extension which can keep your browsing habits in check. Do you spend more time on facebook than on work ? Do you spend time more time in Google Reader or Digg or Hacker News or youtube watching kittens and later wished you had not spent as much time ? Do you want to know how much you spent on Flickr ? If so , Chrome Nanny is for you.
I developed Chrome Nanny when I switched to Chrome and did not find any Chrome Extensions equivalent to Leech Block. You can consider Chrome Nanny as the unofficial Leech Block Lite for Chrome. It has most of the important functionalities in Leech Block and also adds some more. I also want to thank James Anderson (developer of Leech Block) who kindly allowed me to emulate Leech Block's features.
Chrome Nanny allows you to block URLs at certain times in a day or limit to certain number of minutes or both . So you can block facebook from 9AM-5PM or to a maximum of 60 minutes a day or both. You can also group URLs to be blocked into block sets. Unlike Leech Block, you can have as many blocksets as you want. You can use regular expressions to specify the site you want to block. This means you can block any URL with the word "kitten" in it. (See FAQ for details).
If you just want to find how much time you spend on some site, Chrome Nanny can do it too ! Just add the domain in the White Listed URL. Such URLs are not blocked but tracked. Chrome Nanny also has the concept of "Tags" which allows you to group URLs based on your own classification. There is also a "Statistics" page which can chart how you spent your time.
In short, if you have used Leech Block for Firefox , you will be comfortable using Chrome Nanny. Additional instructions are given in the "Instructions" tab of the extension's Options page.
Do use it and tell me your comments ! Please see http://saravananthirumuruganathan.wordpress.com/2010/08/05/chrome-nanny-road-map/ for the list of features planned (and also to request new ones !) .
